Perko 0457DP6 Flush Pro Complete Valve Kit 1 Inch Marine Engine Flushing System

The Perko 0457DP6 Flush Pro Complete Kit makes freshwater flushing and winterizing your inboard marine engine as simple as connecting a garden hose. This complete system permanently installs in-line with the hose leading to your boat's impeller pump, allowing you to flush your engine safely and conveniently—even while the boat is in the water.

Key Features:

• Transparent polymer body allows for visual inspection of water flow during operation
• Durable dual check valve system automatically shuts off hull intake when water pressure is applied
• Stainless steel spring construction for long-lasting marine environment durability
• Fail-safe design automatically closes when garden hose is removed to prevent water entry if cap is not replaced
• Includes winterizing adapter (Part #0499) for easy antifreeze application from a bucket
• Compatible with standard 1-inch marine hose sizes
• Can be used with onboard generators and air conditioning systems
• Made in the USA by Perko

How It Works: Simply remove the Flush Pro cap, attach a standard garden hose, turn on the water and start your engine. The valve automatically responds to water pressure, closing the hull intake and allowing fresh hose water to circulate through your boat's entire cooling system. When finished, remove the hose and replace the cap. For winterizing, use the included adapter to draw antifreeze directly from a container into your engine's cooling system.

This complete kit includes the Flush Pro valve, water inlet thru-hull fitting, 7-foot marine hose, hose fittings, stainless steel clamps, winterizing adapter, and installation instructions.
